Michele Polese, Mischa Dohler, Falko Dressler, Melike Erol-Kantarci, Rittwik Jana, Raymond Knopp and Tommaso Melodia, "Guest Editorial Open RAN: A New Paradigm for Open, Virtualized, Programmable, and Intelligent Cellular Networks," IEEE Journal on Selected Areas in Communications, vol. 42 (2), pp. 241–244, February 2024.


The Open Radio Access Network (Open RAN) vision is based on the three principles of (i) open interfaces; (ii) cloudification; and (iii) automation through closed-loop control. It is a network architecture paradigm embodied and augmented through technical reference specifications of the 3GPP and the O-RAN Alliance. At the centre of Open RAN are open, programmable, and virtualized components, connected to each other through open interfaces that enable closed-loop, data-driven, intelligent control. For instance, the O-RAN Alliance introduced two RAN Intelligent Controllers (or RICs) that connect through open interfaces to the disaggregated components of the RAN, and implement control loops that run at different time scales. The goal of this special issue is to provide a comprehensive overview of fundamental research on algorithmic, architectural, and system issues, as well as on experimental aspects that substantially advance the state-of-the-art on the design of Open RAN systems. Indeed, while Open RAN networks are being deployed in trials around the world, there are still several open issues for both standardization and research, related to the design of data-driven intelligent solutions, efficient control loops, extension of open interfaces and testing, security, and use cases related to private cellular networks, non-terrestrial deployments, spectrum sharing, commercial 5G/6G networks, and evaluation and assessment of fundamental trade-offs, among others.
